Drainage and Waterproofing
Drainage and Waterproofing from Foundation Masters, LLC delivers engineer-designed systems that stop flooding, moisture intrusion, and soil erosion for homes, HOAs, and commercial properties across Florida. As the first engineering firm to pioneer the waterproofing industry in the state, we install permanent solutions backed by a lifetime transferable warranty.
Why Drainage and Waterproofing Is Critical
Florida’s flat terrain, coastal tides, and frequent heavy rain create shallow water tables (often 2–6 feet below grade) and rapid groundwater rise during storms. A single thunderstorm can drop ~3 inches of rain in an hour, pushing the water table up 12–18 inches and loading slabs with hydrostatic pressure.
Because Florida has no statewide waterproofing code (only a rule that finished floor slabs be 12 inches above grade), many structures built at or near grade allow moisture to contact concrete. Over time this destroys vapor barriers, wicks moisture through slabs, warps wood floors, pops tile, and damages finishes.
Check your property’s flood exposure on the FEMA Flood Map Service Center.
Signs You Need Drainage and Waterproofing
- Standing water or soggy areas after storms
- Buckled wood floors or tile popping from slab moisture
- Water stains or efflorescence along baseboards and walls
- Mildew odor or visible mold near slab edges
- Driveway or parking area flooding that drains slowly
Our Waterproofing and Drainage Process
Foundation Masters engineered Florida’s first true structural waterproofing system to keep slabs dry even with high groundwater:
- Excavate ~12″ below the slab edge to expose the footer and wall
- Apply the Seal Tight Waterproofing System to protect below-grade concrete and footings
- Design engineered drainage piping or sump discharge to safely redirect water away from the structure and sensitive soils
- Add gutters and grading corrections to control surface runoff
Results: dry slabs, stable subgrades, and reduced risk of settlement or sinkhole activity.
Parking Lot Drainage and Commercial Waterproofing
We repair and retrofit parking lot drainage systems — rebuilding catch basins, replacing storm piping, and stabilizing subgrades for retail centers, HOAs, and industrial sites. Learn more about our parking lot drainage services.

Frequently Asked Questions — Drainage and Waterproofing
Why do drains still overflow during heavy rain?
When groundwater rises near the surface, drains lose discharge head and can’t empty. Engineered inlets, piping, and sumps restore capacity under high water table conditions.
Do I need waterproofing if my slab is at grade?
Yes. At-grade slabs are exposed to groundwater rise. Our system seals below grade and redirects water so it never touches the concrete.
Can you waterproof an existing building without major demolition?
Yes. We access the slab edge and footer from the exterior, apply the Seal Tight System, and integrate engineered drainage to manage hydrostatic pressure.
Will fixing drainage help prevent sinkholes?
Controlling water prevents soil washout into natural limestone voids, reducing a key trigger for subsidence and sinkhole activity.
Do you service commercial properties?
Absolutely. We design and repair catch basins, storm pipes, and subgrades for retail centers, HOAs, high-rises, and industrial sites.
